The version of containerd installed on the remote host is prior to 1.6.19-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2NITRO-ENCLAVES-2023-023 advisory.

    containerd is an open source container runtime. A bug was found in containerd's CRI implementation where a     user can exhaust memory on the host. In the CRI stream server, a goroutine is launched to handle terminal     resize events if a TTY is requested. If the user's process fails to launch due to, for example, a faulty     command, the goroutine will be stuck waiting to send without a receiver, resulting in a memory leak.
    Kubernetes and crictl can both be configured to use containerd's CRI implementation and the stream server     is used for handling container IO. This bug has been fixed in containerd 1.6.12 and 1.5.16. Users should     update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted     images and commands are used and that only trusted users have permissions to execute commands in running     containers. (CVE-2022-23471)

    containerd is an open source container runtime. Before versions 1.6.18 and 1.5.18, when importing an OCI     image, there was no limit on the number of bytes read for certain files. A maliciously crafted image with     a large file where a limit was not applied could cause a denial of service. This bug has been fixed in     containerd 1.6.18 and 1.5.18. Users should update to these versions to resolve the issue. As a workaround,     ensure that only trusted images are used and that only trusted users have permissions to import images.
    (CVE-2023-25153)

    containerd is an open source container runtime. A bug was found in containerd prior to versions 1.6.18 and     1.5.18 where supplementary groups are not set up properly inside a container. If an attacker has direct     access to a container and manipulates their supplementary group access, they may be able to use     supplementary group access to bypass primary group restrictions in some cases, potentially gaining access     to sensitive information or gaining the ability to execute code in that container. Downstream applications     that use the containerd client library may be affected as well. This bug has been fixed in containerd     v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue.
    Users who rely on a downstream application that uses containerd's client library should check that     application for a separate advisory and instructions. As a workaround, ensure that the `USER $USERNAME`     Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to     `ENTRYPOINT [su, -, user]` to allow `su` to properly set up supplementary groups. (CVE-2023-25173)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
